Abstract

1363176 Dialyser UNITED STATES ATOMIC ENERGY COMMISSION 25 Sept 1972 [10 March 1972] 44157/72 Heading B1X A dialyser comprises rectangular housing 1, pleated semi-permeable membrane 6 within the housing, all edges of the membrane being sealingly embedded in plastics material 11 constituting at least a portion of the housing, support members 7 disposed within all pleats on one side only of the membrane, means 2, 3 for passing a first fluid through a first chamber on one side of the membrane in a direction generally parallel to the creases of the pleats and means 4, 5 for passing a second fluid through the second chamber countercurrent to the first fluid. The pleated membrane may be inserted into a preconstructed rectangular casing (Fig. 2, not shown) and a fluid plastics material injected into the casing to fill the first and last pleats and to seal the end edges of each pleat. In an alternative embodiment, the openings to the supported pleats may be covered by barrier sheets 18, 19 (Fig. 5) of for example polycarbonate or polypropylene, the membrane assembly placed in a rectangular mold having studs between the membrane and the mold wall extending vertically from the first pleat to the last pleat to form eventually the inlet and outlet passages and the plastics material 11 injected into the mold to form the entire housing.
